ChangeKit

ChangeKit is a simple framework that integrates with your iOS and Android apps, along with your server, to make data usage efficient.

ChangeKit is a work in progress tool, and should not be deployed in production until specified in this README.

ChangeKit requires the mysql library. To initialize ChangeKit, simply:

const changekit = require("changekit")({
   mysqlDatabase: database
});

From here, whenever a data request is made, ChangeKit should be queried to see if the client's cached data is outdated. Using express would look like this:

// Listen for localhost:3000/home/v1/get
app.get("/home/v1/get", function(req, res) {
    // If you have a resource that is frequently accessed, consider caching it
    changekit.stubForResource("home").then((stub) => {
        // If there is no update required, inform the client 
        if (!changekit.shouldUpdate(req, stub)) {
          res.status(200).json({updateRequired: false})
          return
        }

        // Now load data that is used to power this endpoint
        res.status(200).json({updateRequired: true})
    })
});

If you aren't using express, there will be an alternative method for you to call soon.

Again, this is a work in progress tool, and it should not be deployed to production until specified in this README. Check back soon for updates.
